electrical box in granny flat - what can I learn?

Planning a 200w LED grow in my granny flat, would probably be using a decent 6" inline fan to vent, speed adjusted using a variac... just wondering what I can learn from this pic that might help guide my build? Wouldn't mind an EC controller of some sort, adjusting fan speed and maybe a heater to keep temps stable... soil grow.

So what do all those switches do? And what are the numbers, etc?

Any advice would be much appreciated.

Cheers.

Those are breakers.

Breakers are used to protect your house from fire.
All breakers have a current rating (AMPS) that are matched to the gauge of wire used in a circuit.
The numbers are circuit identification.

This pic shows that the oven is on circuit N3 and is rated for 16 amps at 230 volts.

If you do not know what you are doing you need to hire an electrician, people can die from mistakes.

200w led and a huge fan...?

you may be surprised to find

LED don't give of that much heat

you should be able to plug ur led and small fan into N4 & N5 circuits

with no issue

most if not all 240v circuits can handle 2400 watts at 10amp

good luck

Thanks for the advice, guys. Clearly I don't know what I'm doing... I just wanted to know if it's safe to run a 200w light and a decent sized fan off the power system installed in this granny flat... looks like I should be okay? I found a power outlet in the attic that I'm planning to attach an 8 outlet socket to, and run everything off that... should be ok?

Just plug it into the wall man. If it overloads it will trip the breaker. But it sounds like you well within the range.

I would try to run the light off a separate circuit to the fans myself but beggars cannot be choosers.
